An audio waveform visualizer renders the amplitude of an audio signal over time as a graphical image. The horizontal axis represents time while the vertical axis shows amplitude — loud sections appear as tall peaks, quiet sections as narrow lines near center.
This tool uses the Web Audio API built into modern browsers to decode your audio and render the waveform on an HTML5 Canvas — entirely in your browser, no server upload needed.
Works with MP3, WAV, OGG, FLAC, AAC, M4A, and more.

The waveform shows amplitude over time. Tall spikes = loud audio; flat sections near center = silence.
